The benefits of Intel platform based computing: How your PC configuration affects Skype* Internet phone quality
Intel commissioned Principled Technologies to study the audio quality of Skype* Internet phone calls (Voice over IP, or VoIP calls) on business PCs performing typical user functions. As PCs become alternatives to phones and provide enhanced calling features such as call forwarding, conference calling, and multiple telephone numbers, Internet phoning over PCs will become increasingly common.
| A 2005 business PC with an Intel® Pentium® D Processor 840 with dual-core processing |
| A roughly three-year-old PC with an Intel® Pentium® 4 Processor 2.0 GHz |
|
We tested audio quality and system response time using a common scenario in which a user is working with two Microsoft* Office 2003 programs while he is on a Skype Internet conference call and a scheduled virus scan is running in the background. This type of scenario is known as "multitasking" because the PC is performing multiple tasks at once, even though the user might be focusing on only one or two of the tasks at any given time.
| The PC with an Intel® Pentium® D Processor 840 with dual-core processing delivered high fidelity Skype* Internet phone calls that we found to be nearly flawless despite heavy system loads. |
| By contrast, the three-year-old PC experienced a significant number of relatively long audio glitches under the same workload. |
| The newer PC also delivered much better application response time when facing the sustained load of an Internet conference call and multiple applications running at the same time. |
